  1. (988−12−5.12).(99+88+77+66)
    =[988−12.(1+5)].11.(9+8+7+6)
    =(988−12.6).11.30
    =(988−72).330
    =916.330
    =302280

  2. Giải đáp + Lời giải và giải thích chi tiết:
    $(988 – 12 – 5 . 12) . (99 + 88 + 77 + 66)$
    -> $(998 – 12 – 60) . (11 . 9 + 11 . 8 + 11 . 7 + 11 . 6)$
    -> $926 . [(11 . (9 + 8 + 7 + 6)$
    -> $926 . (11 . 28)$
    -> $926 . 308$
    -> $285208$
